it was snowing the other day and i turn on
my rear window wiper and it got stuck ok fine so i turn it off
when i got home my whiper was still attach but it was now on the
body of the car and not the window[:0]
and now when i turn it on it just makes a clicking sound

What did i brake and how hard is it to fix ?
what do i need to what out for so the dealer fixes it right ???[:I]
do they have to take the rear hatch of ?? will it rattle after they put it back on ???
